1 Claim. (01'. 24-19) This invention relates to a clamp for use about a hose or similar object. 1

The object of the; invention'is to produce a clamp of the character described, which will be simple and economical inconstruction and facile in operation. r v

A preferred embodiment of the invention'is illustrated in the accompanying drawing.

Fig. 1 is a top plan viewof the clamp; Fig. 2 is a vertical section on line.2-2,

Fig. 1, Fig. 3 is an end elevational view;

. Fig. 4'is a perspective of a dog which is apart of the clamp; and

Fig. 5 is a perspective view-of a nut employed in the clamp.

' A strap I has a bracket comprising ears 2 laterally extending at or near one end of the The other end of the strap I. when by a lug 4 on a dog"5.,

The dog 5 is a part of an engaging assembly which includes the dog, a thumb screw 6 and a nut i, all of which is pivotally supported by a and between the ears 2.

The nut 1 has a pair of extending trunnions 8 which engage in" s10ts'9, one in each of the ears 2. The screw 6 is threaded in thenut 1 while the dog 5 is swivelled on its outer. end, as bestshown in Fig. 2.

The pivotal connection between the advancing assembly just described and the ears 2 is provided' by means of a slot 9, sinc the slots provide necessary clearance when the advancing screw assembly is rotated.

In operation'we may assume that the clamp is fore economical to manufacture.

in the position shown in Fig. '3 about an object such as a hose. The screw and its assembly is then rotated in a counterclockwise direction, the lug 4 engaging in one of the holes 3 and advancing the. free end of the strap I. Then the screw may be. turned to complete the tightening of the strap I. The turning of the screw will advance'the dog 5 in a manner readily understood from the foregoing description and the drawing.

It will be obvious from the foregoing description-that the invention accomplishes its object.

The. device is simple in construction and there- That it is .facile in operation can readily be seen. Various changes in the detailsof construction, with in the scope of the appended claim, may be made without departing from the spirit of this in- .vention. Improvements may be added thereto while retaining the functions and results of the invention.

We claim:

A clamp including a strap adapted to surround an object such as a hose, laterally extending ears at one end of the strap, the other end having one or more holes therethrough and overlapping the first end, a nut pivotally mounted on and between the ears, a screw threaded in the nut, 'a dog swivelled on the outer end-of the screw and adapted to engage in said holes, constructed and arrangedwhereby the nut with the screwand dog may be rotated as a whole 0n the pivot of the nut to engage the dog in one of said holes and tightenthe strap about the object on a which it may be placed, and then the strap may be further tightened by rotating the screwand thereby advancing the dc EUGENE F.
